ARCHITECTURE
The Broadcom Advanced Server Program is implemented as an NDIS intermediate driver (see Figure 2). It operates below
protocol stacks such as TCP/IP and IPX and appears as a virtual adapter. This virtual adapter inherits the MAC Address of
the first port initialized in the team. A Layer 3 address must also be configured for the virtual adapter. The primary function
of BASP is to balance inbound (for SLB) and outbound traffic (for all teaming modes) among the physical adapters installed
on the system selected for teaming. The inbound and outbound algorithms are independent and orthogonal to each other.
The outbound traffic for a particular session can be assigned to a given port while its corresponding inbound traffic can be
assigned to a different port.
